DCA-600SSV — GENERAL INFORMATIONDCA-600SSVWhisperwatt Series FamiliarizationGeneratorThe MQ Power Model DCA-600SSV is a 528 kW generator(Figure 5) that is designed as a high quality portable (requiresa trailer for transport) power source for telecom sites, lightingfacilities, power tools, submersible pumps and otherindustrial and construction machinery.Engine Operating PanelThe “Engine Operating Panel” is provided with the following:■ Tachometer/Hour Meter Gauge■ Water Temperature Gauge / Water Temp. Alarm Lamp■ Oil Pressure Gauge / Oil Pressure Alarm Lamp■ Charging Alarm Lamp■ Fuel Level Gauge / Low Fuel Warning Alarm Lamp■ Pre-Heat Button / Pre-Heat Lamp■ Air Filter Alarm Lamp■ Engine Speed Switch■ Battery Switch■ Emergency Stop ButtonGenerator Control PanelThe “Generator Control Panel” is provided with the following:■ Frequency Meter (Hz)■ AC Ammeter (Amps)■ AC Voltmeter (Volts)■ Ammeter Change-Over Switch■ Voltmeter Change-Over Switch■ Voltage Regulator■ Panel Light/Panel Light Switch■ 3-Pole, 1,600 amp Main Circuit Breaker■ Engine Control Unit (Computer Controlled)■ “Control Box” (Located Behind Gen. Control Panel)■ Automatic Voltage Regulator■ Current Transformer■ Over-Current Relay■ Voltage Rectifer■ Starter Relay■ Voltage Change-over BoardOutput Terminal PanelThe “Output Terminal Panel” is provided with the following:■■■■■■■■Three 120/240V output receptacles (CS-6369), 50AThree auxilliary circuit breakers, 50ATwo 120V output receptacles (GFCI), 20ATwo GFCI circuit breakers, 20AFour output terminal boards (3Ø power)Ground terminalBattery Charger (Optional)Water Heater (Optional)Open Delta Excitation SystemThe DCA-600SSV generator is equipped with the state ofthe art "Open-Delta" excitation system. The open deltasystem consist of an electrically independent winding woundamong stationary windings of the AC output section.There are four connections of the open delta A, B, C and D.During steady state loads, the power from the voltageregulator is supplied from the parallel connections of A to B,A to D, and C to D. These three phases of the voltage inputto the voltage regulator are then rectified and are theexcitation current for the exciter section.When a heavy load, such as a motor starting or a shortcircuit occurs, the automatic voltage regulator (AVR)switches the configuration of the open delta to the seriesconnection of B to C. This has the effect of adding thevoltages of each phase to provide higher excitation to theexciter section and thus better voltage response during theapplication of heavy loads.The connections of the AVR to the AC output windings arefor sensing only. No power is required from these windings.The open-delta design provides virtually unlimited excitationcurrent, offering maximum motor starting capabilities. Theexcitation does not have a "fixed ceiling" and respondsaccording the demands of the required load.EngineThe DCA-600SSV is powered by a 4 cycle, water cooled,turbocharged VOLVO Model PENTA TAD1642GE DieselEngine. This engine is designed to meet every performancerequirement for the generator. Reference Table 2 for enginespecifications.In keeping with MQ Power's policy of constantly improvingits products, the specifications quoted herein are subject tochange without prior notice.Electronic Governor SystemThe electric governor system controls the RPMs of the engine.When the engine demand increases or decreases, thegovernor system regulates the frequency variation to ±.25%.Extension CablesWhen electric power is to be provided to various tools orloads at some distance from the generator, extension cordsare normally used. Cables should be sized to allow fordistance in length and amperage so that the voltage dropbetween the generator and point of use (load) is held to aminimum. Use the cable selection chart (Table 6) as a guidefor selecting proper extension cable size.PAGE 20 — DCA-600SSV — OPERATION AND PARTS MANUAL — REV. #0 (07/13/09)
